Insulting Seller

I work at a Bookshop which has it's own stock items and records. I am an authorized administrator of the account. Supplier invoices to support it. These books are listed on Bidorbuy. This account went through a verified user successfully and 100% rating. No Problems. I also own my own account on which I sell goods of my own with their own invoice history to support the documents. This account also went through a verified user process successfully (which costs you a sum to do). The profile also has a 100% customer satisfaction rating. Bidorbuy claims that this cannot be done whatsoever
